All modern cars have a safeguard in place called a rev limiter so that you
cannot blow up your car without severely circumventing the safeguard.
Network devices in general should not "crash" because of a limit being
reached. If they become unresponsive, sure. But crashing and process
crashing should not happen. If it does, there is a undesired or unexpected
outcome. That is called a bug.

No I wouldn't. :)
If you try to use a device for more than it was designed to do and it
breaks, that's not a bug. What would you have the router do when it reaches
a state beyond what its suppose to do? The router's response at this point
is unpredictable....
If you blow your car's engine because you over-rev it and it blows, are you
going to call that a bug??

You think running a router crashing based on your testing isn't a bug? That
isn't a bug? What would you call it?
Even if the router's max AES throughput is 65mbps (which no one here is
discussing and has nothing to do with the original poster's question), when
it hit that limit and crashed, that's not a bug?

no one mentioned anything about a bug..
we wanted to see if the 3845 could handle a 100mbps connection. so in our
lab, we pushed traffic to the 3845. as i stated before, we were encrypting
the traffic. on demand, we could crash the router. @ ~65mbps, the router
crashed.
as scott mentioned, one would look at you twice if you tried to use the 3845
on a >100mbps link.

What does a bug in specific code have to do with throughput on that

I've pushed more traffic than that (non-encrypted) on 3845s.
Only hooking up a DS3 to a 3845 is really good for your partner and not much
else.
The 3845 is faster than an NPE-400. I'm pushing 100mbps on a NPE-400 right
now without any problems. And, not peak traffic load. And, 2 full BGP
feeds.

256mbps of throughput on a 3845??? not likely.
you shouldn't put more than a ds-3 to a 3800. ~50mps is the best the router
can do wire rate...
i've crashed a 3845 pushing ~65mbps (w/encryption) and i could reproduce the
crash on demand using a traffic generator.
